Embodiment Construction

[0025] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] see figure 1 , which is a block diagram of the method for retrieving massive video content of the present invention. As shown in the figure, the massive video content retrieval method includes the following steps:

[0027] S1, dividing the video file into several shots;

[0028] S2. Extract the features of each shot to obtain a feature space that can reflect the content of the shot, and use the feature space as a basis and basis for mass video retrieval.

[0029] The following describes the above steps in detail:

[0030] The step S1 is to divide the video file into several shots....

Abstract

The invention discloses a method, system and mobile terminal for searching massive amounts of video content. The method includes the following steps: segmenting videos into scenes, achieving feature extraction for all the scenes, and obtaining a feature space capable of fully reflecting the content of the scenes of the video, wherein the feature space will serve as a basis for accurately searching a huge number of videos. The feature extraction is composed of visual feature extraction of key frames and kinetic feature extraction of the scenes. Thus, visual information of the videos is fully utilized, precise searching of massive amounts of video data can be improved, and experience of a user can be improved. Characteristics of the huge number of videos are found, the method of key frame extraction is used, module optimization is conducted, the technical bottleneck that a video depends on a text tag for being searched is overcome, research based on video content searching is provided, new data representation and data models are introduced, and precise searching for the massive amounts of video data is achieved. The method, system and mobile terminal for searching the massive amounts of video content can process the massive amounts of video data, and meanwhile meet video application characteristics of precise searching performed by the user.

Description

technical field [0001] The invention relates to the technical field of video retrieval, in particular to a video content-based massive video content retrieval method, system and mobile terminal. Background technique [0002] With the development of multimedia coding, multimedia processing and network transmission, video retrieval technology has become an important issue in the field of database and information retrieval. The key lies in the effective organization and precise retrieval of video information. Furthermore, the current Internet is becoming a huge data warehouse. Even video retrieval based on databases has to face the problem of huge data volume and complex structure. Relying on video text tags for video retrieval will not only affect the retrieval results, Moreover, the retrieval process does not make full use of the visual information of the video, resulting in repeated retrieval results, and the traditional serial method cannot meet the practical requirements i...
